A high-energy environment is one in which the water is fast-moving and agitated, able to carry particles of large grain sizes; typically this occurs in shallow lakes & seas and in rivers, as well as deserts. Conversely, a low-energy environment is one in which the water can be very deep and quiet; it can only carry the finest grain sizes (if any!).
